  1. My choice would be the Chorus and try both your amplifiers to see how they will sound on the Chorus then use the one you like best.
  2. here is an honest set of reliable measurements done on a klippel system by a competent technician. https://www.erinsaudiocorner.com/loudspeakers/klipsch_forte_iv/
  3. it was a blessing that you had so long with you pup to love each other.
  4. please let us know how things go. prayers and good vibes your way.

  6. hang tough prayers and good vibes your way, remember good things can happen too.
  7. if your cones are cracked you can repair them to good as new. I repaired cracked cones with loctite black max. Expensive but a truly superior adhesive.
  8. there are many here I am sure that hope they don't at least not now anyway.
  9. Its not the amp(s) that has the biggest impact here it is the active crossover/EQ and DSP control which make the real difference. You still need to have chosen good drivers and do all the same engineering that are required to make a good loudspeaker. No argument from me about the value of a good amplifier but an amplifier can't fix the problems that a DSP system can.
  10. yes still in Calgary but not presently. I am helping my daughter with two little ones in Nova Scotia where I will be for another year. I would not mind a visit to YK to hear your Walsh but I am going to be traveled out by the time I get back home to Calgary. I am helping my brother with advice to refurbish an old pair of JBL SR mkll 4726a two way PA speakers now we are in the final tweaking phase. I am astounded at how they have turned out. When I get back the plan is to begin a build of a pair of CBT24 shaded line array speakers based on Don Keele's work using a single array of SB Acoustic 2.5" full range drivers so I will be busy. Here is a photo of what the JBL look like today.
  11. thanks for getting another year older and wiser. all the very best wishes on your birthday!
  12. that's the one I could not find it thank you for picking it up an excellent machine should last a long time.
  13. you can buy the now top of the line Sony bluray player for a few hundred dolllars plays everything sound excellent as a transport. sorry I forgot the model.
  14. if you mean that you want to remove the passive radiator in your T500,s then bock off the open hole and run the T500 as a sealed cabinet and augment the low bass with and active (powered) sub then sure I would say that was a good idea. But if you are suggesting that you remove the passive radiator from the T500 then install a second woofer into where the passive was and run it in either parallel or series with the existing woofer then no that would be a non productive thing to do since you would need to re design your speaker to make such an idea work, it is just not a useful way for you to spend your time or money. In case you are not sure about what a passive radiator does it has the exact same function as a reflex vent in that it is a resonating mass which couples in antiphase to the woofer to provide damping/control to the woofer when it plays low enough to reach the system resonance. It is like an acoustical break which is frequency controlled it couples with the woofer adding a mass to the woofer which then alters (lowers) the resonant frequency of the woofer. This process happens over a very narrow band of frequency of only 5 or 6 Hz. and without it to damp or control the woofer it would reach the system resonant point and begin to resonate at full excursion and if left undamped would proceed to tear itself to pieces. I hope this helps you to understand things a little better. If you want more bass add a sub or two. removing the passive and blocking it off with a plywood blank would turn your speakers into a sealed box design. A reflex box whether it is designed with a vent or a passive radiator has a roll off of 24 db per octave below the tuning frequency while a sealed box rolls off at only 12db per octave below system or box resonance, so you will actually get lower frequency extension and more useful output with the box sealed. This would involve re damping the cabinet. There is a caveat and that is that almost all reflex designs have an intentional hump in the bass response somewhere prior to system or box resonance this is intended to make the woofer provide a little more umph. With a sealed box you will loose the additional bass hump in the response but since it rolls off so much slower you will attain lower bass frequency extension. There is no "free lunch" you decide what you want to achieve. Good of you to ask your question because you are not the only person to have wondered about this. The more questions you ask the more you will know and hopefully the easier your audio journey will be. Remember the fun is in the journey and not the destination.
